Role of activating transcription factor 4 in the hepatic response to amino acid depletion by asparaginase [PDF]
The anti-leukemic agent asparaginase activates the integrated stress response (ISR) kinase GCN2 and inhibits signaling via mechanistic target of rapamycin complex 1 (mTORC1).

Role of Activating Transcription Factor 4 in Murine Choroidal Neovascularization Model [PDF]
Neovascular age-related macular degeneration (nAMD) featuring choroidal neovascularization (CNV) is the principal cause of irreversible blindness in elderly people in the world. Integrated stress response (ISR) is one of the intracellular signals to be adapted to various stress conditions including endoplasmic reticulum (ER) stress.

Activating transcription factor 4
Activating transcription factor 4 (ATF4) belongs to the ATF/CREB (activating transcription factor/cyclic AMP response element binding protein) family of basic region-leucine zipper (bZip) transcription factors, which have the consensus binding site cAMP responsive element (CRE). ATF4 has numerous dimerization partners. ATF4 is induced by stress signals

Activating transcription factor 4 regulates stearate-induced vascular calcification [PDF]
Previously, we reported that stearate, a saturated fatty acid, promotes osteoblastic differentiation and mineralization of vascular smooth muscle cells (VSMC).

Upregulation of the coagulation factor VII gene during glucose deprivation is mediated by activating transcription factor 4. [PDF]
BACKGROUND: Constitutive production of blood coagulation proteins by hepatocytes is necessary for hemostasis. Stressful conditions trigger adaptive cellular responses and delay processing of most proteins, potentially affecting plasma levels of proteins ...

Epigallocatechin Gallate Ameliorates Granulosa Cell Developmental via the Eukaryotic Initiation Factor 2 Alpha/Activating Transcription Factor 4 Pathway in Hyperthyroid Female Rats [PDF]
Follicular development is recognized as a highly complex biological process regulated by multiple factors. Thyroid hormone (TH) is considered one of the key regulators of female reproduction, and its dysregulation can significantly impair follicular ...

Pharmacological Disruption of Phosphorylated Eukaryotic Initiation Factor-2α/Activating Transcription Factor 4/Indian Hedgehog Protects Intervertebral Disc Degeneration via Reducing the Reactive Oxygen Species and Apoptosis of Nucleus Pulposus Cells [PDF]
Excessive reactive oxygen species (ROS) and apoptosis in nucleus pulposus (NP) cells accelerate the process of intervertebral disc degeneration (IDD). Here, we integrated pathological samples and in vitro and in vivo framework to investigate the impact ...

Regulation of cellular immunity by activating transcription factor 4. [PDF]
Activating transcription factor 4 (ATF4) is a DNA binding transcription factor belonging to the family of basic Leucine zipper proteins. ATF4 can be activated in response to multiple cellular stress signals including endoplasmic reticulum stress in the event of improper protein folding or oxidative stress because of mitochondrial dysfunction as well as

Activating transcription factor 4 regulates osteoclast differentiation in mice [PDF]
Activating transcription factor 4 (ATF4) is a critical transcription factor for osteoblast (OBL) function and bone formation; however, a direct role in osteoclasts (OCLs) has not been established. Here, we targeted expression of ATF4 to the OCL lineage using the Trap promoter or through deletion of Atf4 in mice.
